that light and motion seca 1700 enduro has me excited
I am thinking of running it on my bars with the cygolite tridenx 750 xtra on my helmet
nothing like a good 3 hour night ride
just need to pull the trigger

The winner is the Magicshine MJ-872, which is also the fifth cheapest light in the test. The MJ-808 is the second cheapest light. Magishine is a Chinese company, so you expect them to be cheap, perhaps at the cost of less reliability. There are a few USA based distributors that offer a warranty. Outside of the top 5, the lights only offer a 4.54 to 1.23 lumens to dollar ratio. That is less than half of the MJ-872. Maybe next year they will break the 10 lumens/dollar ratio.

Obviously there are other factors to consider in a light, such as warranty, beam shape, runtime, water resistance, etc.

I see the lumens figures are in for the Gloworm X2 - 1148 lumens in the integrating sphere test. That puts it straight into 3rd place on the lumens per $ chart with a result of 5.24

Hey Francois---Do you have an updated version of this spreadsheet you can post, that includes the latest lights (especially Niterider)? I can't find it anywhere and it is really helpful to see all the data points in one sheet like this. Thanks!

p.s. The Magicshine 872 has been downgraded to 920 lumens instead of 1200. After further testing, it would drop precipitously to 920 lumens. No amount of high speed fan could get the output back up. It does seem like they are overboosting the light for the first 30 seconds to make it look good in photos and measurements.

Not that it really matters that much (since there are so many lights that you could test, especially cheap knock-offs) but maybe you can test the MJ-856. It is the same light as the MJ-872, but with improved heat-sinking. I have one and never experienced a power stepdown even during long rides.

I just tried it out and it does a lot better. It ran at about 117 lux without a fan and it dropped down to about a 104 lux after a couple of minutes. I then put a fan on it and it went back up to 112. So definitely this is a heat issue.

This is good news as I picked one of those up after your initial review. It's still going strong and works great as a bar light.

On the main Shoot-Out page you list the price as $250. That price is also used in the spreadsheet, graphs etc.

Clicking on the link takes us to the 2012 review, listing the price as $110.

I don't know what the current price of the 350 is, but Canada's Mountain Equipment Co-op lists the Expilion 700 at $129. The 350 is no longer listed on Cygolite's product page, so I suspect it has been discontinued.

Other CygoLite models in the 300-420 claimed lumen range are now at $50 to $70.

Hey Francois, Got a quick question for you. Are you planning on adding / reviewing additional lights to the database in the future, as they become available ? Reason being. It sure would nice to see how the Gloworm X1 with the new XML-U3, stacks up against the competition...

The Gloworm X1 has just arrived here - seriously impressive. In the past you needed a large reflector to get decent throw but the hotspot on the X1 is much stronger than a reflector based XM-L which I've wall tested it against.

Hi Guys , I am new to your forum and found this thread interesting as I do a lot of trails night riding, here in Sussex in England. I am surprised Francois not to see any of the Bikeray lights in your table. Quality/versus lumens/versus price is great.
We have a lot of guys MTB section ridding with the RAY III or RAY IV

Great wright up. Nice R&D. Talk about giving back to the community. In light of the Majic shine MJ872. Did you happen to know what battery pack utilized in any of your notes? I noticed the light now sells with a claimed improved battery pack... Currently, looking for a decent affordable light. I noticed there seemed to be a anomaly with this light.
